Ok, did that. Twice. No response. Evidently complained about that in the wrong place and got this warning:
Note for member
Please keep in mind the suggestions forum aren't meant for asking for support.
To get your clan leadership change, you have to file a support request _from the leaders account_ with the title (important): "Clan Leadership Change" and in the contents:
Your playerID:
New leader playerID:
The desire to have your clan leadership change.
Once requested properly, please be patient. it's not an official feature and is currently manual work, if you're in any hurry, we suggest rerolling (having leaders leave) or starting a new clan instead.
Ok, went to account settings and entered the info, only there is no spot for the title.
So this leaves me with the question of which support are we supposed to contact- the support here on the forum or on your actual in-game account?
Also, a leader leaving changes leadership to the next highest rank if I'm not mistaken. That leaves the other players in the same position I'm in now.
